FOLDING CENTERMBOARD.

SPECIFICATION 'forming part of Letters Patent No. 377,134, dated January 31,182 8.

Application liled June 17, 1887.

To all whom, it may concern.-

Be it known that I, AsHBnLL BARNUM, a resident of Green Island, in the county of Albany and State of New York, have invented certain new and useful Improvements in Folding Center-Boards, and I do hereby declare that the following is a full, clear, and exact description of the invention, that will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

Similar letters refer to similar parts in the several figures therein.

My invention relates to improvements in folding centerhoards; and it consists of the novel construction and combination of parts hereinafter described, and pointed ont in the claims.

The objects of the invention are set forth in connection with the following` description.

Figure l of the drawings is a side elevation of a boat provided with my ilnproved centerboard folded within a slot in the keel of the boat. Fig. 2 is a similar view showing the board unfolded and projecting from the keel. Fig. 3 is aview in perspective of one of the board-sections detached. Fig. 4 is a crossseetion of same,taken at the broken line .r x in Fig. 3,011 enlarged scale. Fig. 5 is a horizontal section of a portion of the boat, taken at the broken line a; m in Fig. 8, showing the board folded, as shown in Fig. l. Fig. (i is a similar view showing the board unfolded, as shown in Fig. 2. Fig. 7 is a plan view of a sheet-metal blank, which is bentinto the form shown in Fig. I3 in forming the board-sections. Fig. 8 is a cross-section taken at the broken line :v in Fig. 5, showing the sections exaggerated in thickness and shape, for convenience of illustration. Fig. 9 is a similar cross-section taken at broken line x a; in Fig. G.

'My improved center-board B is shown in position for use on the boat A in Fig. 2, and is adapted to be folded up when out of use and housed in a slot, K,in the keel K. It may be thus folded wholly within the keel, as shown in Fig. l, where it will be wholly protected from injury in shallow Water, and by reason 0f its novel construction can be wholly housed Serial No. 241,594. (No model.)

Within the keel without any projections withi n the boat.

The center-board is made up of sections C, preferably ofsheet metal, pivoted at their ends upon supporting and connecting slats or bars F and G, as will be more fully explained hereinafter. Blanks are first struck out or cut from sheet metal of about thc form shown in Fig. 7. These blanks are then bent along the broken lines shown in Fig. 7 into the form shown in Figs. 3 and 4, in which the walls C' O are about right-angular to the unbent portion and in cross-sectional outline parallel to each other, but convergentlongitudinally from one end of the section C to the other, presenting atrough-like appearance, having the opelr ing gradually contracted from one end to the other ofthe section. The side walls are provided with pivot-apertures C2 and C3, one in each end. The contracted ends of the several sections are thus pivoted upon a slat or bar, G, inserted between the side walls ot' the contracted ends through the pivotholcs Gs in such a manner that the side walls of each section slightly overlap the bottom or unbent portion of each succeeding contiguous section. The other ends of the sections are pivoted in a similar position to two bars,F F,placed on the outer side of the walls C, each wall being independently pivoted upon its contiguous bar F by means ofthe rivets or pivots R, except that the first pivot, It, may extend through from one bar F to the other, forming a pivot or fnlcrum for the operating-lever L, one end ot' which is secured to the section so pivoted at R2, the position ol' theleverbeing shown by dotted lines in Fig. G. rlhe other end of the lever is connected by link L with the stein H', which passes up through an ordinary stuffingbox, J, into the boat, and may beprovided with any convenient handle, as H. rlhe bars F are provided with rightangular flanges F', by

which they may be secured to the bottom ol' the slot in the keel, or to the floor-timbers E and keelson D, when the slot passes entirely through the keel, as by the screws S.

It will be seen by an inspection of Fig. 9 that the sections are thus firmly secured upon each side, and that their stability or power of resist ing a lateral or side strain is proportional to the relative lengths of the altitude and base IOO UNITED STATES PATENT OFFICE.

SOAP COMPOUND.

SPECIFICATION forming part of Let-ters Patent No. 377.135. dated January 31. 1998- Appneaaon fneaMarch 5,1887. seriainaczaaii. (Spaink-ns.)

To aZZ wwm it may concern:

Be it known that I, FEEDRICK C. BAUER, of Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented a new and Improved Soap Compound, of which the following is afull, clear, and exact description.

My improved soap compound is designed for the use of mechanics, laborers, and others requiring a soap that will quickly and thoroughly remove grease and dirt from the hands and face.

My invention consists in combining with nelygranulated porous materialsuch as sawdust-a quantity of soap of any approved manufacture.

In carrying out my invention I take granulated porous material, preferably sawdust, and screen it to secure uniformity of tineness, and I take hard soap of any desired quality and dissolve it in water, in about the proportion of a quarter of a pound of soap to a pint of water, and I boil the same until the solution is complete. I thoroughly mix the sawdust with the soap solution, and afterward spread it out to dry, and when dried it is ready for use.

My improved soap compound is used by moistening it with water and rubbing it thoroughly upon the skin.

I am aware that cakes or bars of soap have contained sawdust as one of their constituents, and I do not claim the same as of my invention; but I am not aware that a soap in granular form has been composed of sawdust or equivalent vehicle chargedl with soap.

Having thus fully described my invention, I claim as new and desire to secure by Letters Patent- A granular soap compound consisting of a porous vehicle-such as sawdust-charged with soap, substantially as set forth.
